ECG

Electrocardiography (ECG) is the technique of monitoring the electrical function of the heart. Its results are presented in the electrocardiogram (ECG or EKG), which is a graph of time in the horizontal axis and voltage in the vertical axis. ECGs are used to detect any dysfunctions in the heart rhythm (e.g. arrhythmias) or the electrical profile of the heart’s contraction (e.g. specific alterations of the ECG are present in conditions such as the acute myocardial infarction, hypertrophic cardiomyopathy).
